Abstract: A play system floor includes a frame defining the periphery of an area to be floored and a webbed flooring constructed of a webbing material extending between the frame members. The webbing material has an optimal predetermined stretch coefficient at which it retains its resiliency, while resisting sagging. The webbed flooring is sized using the stretch coefficient whereby the dimensions of the webbed flooring when stretched substantially correspond to the dimensions of the area to be floored. The webbed flooring is stretched to the dimensions of the area to be floored and secured to the frame. The floor is stretched to the dimensions of the area to be floored by positioning a bar through loops on each side of the weaved flooring, and applying tension to each bar. The webbed flooring is secured to the frame by attaching each bar to the frame using clamps, bands, or other attaching devices. Tension to each bar is applied by operating a screw-actuated clamping member to tighten the bar against the frame.

Abstract: A sign face frame structure for universal mounting on generally a vertically extending support. The body of the sign face frame is simple to manufacture and is formed of extruded aluminum bar stock in a manner to have a rigid mounting flange or leg surrounding the sides and bottom of the perimeter of the face frame, the flange being also provided for attaching the sign to the support. The sign face frame includes a semi-circular member to interfit with a receiver of various mounting designs. This semi-circular receiver may be incorporated into a sign base frame embodiment as an appendage or it may be provided as an independent part to be attached to a sign frame or building for the installation purposes of a sign face. The semi-circular receiver is designed for supporting the full weight of the face frame during installation until such time that sides and bottom mounting flanges or legs are attached or mechanically fastened to add relief to the weight bearing or attachment bond of the assembly.

Abstract: An extruded longitudinally-pliable but uprightly rigid plastic edging strip may be affixed to the side of the outer edge of a shaped back mounting panel. The tall thin cross section of the planar strip allows its longitudinal axis to bend sideways to follow the curved edge of the shaped backing. Once in place, canvas or like fabric may be stretched over the edging strip and lie in a horizontal plane that is vertically elevated from the horizontal plane of the backing panel, whereupon the canvas will not contact the backing panel. Suitably shaped injection-molded thrust-support brackets placed at spaced horizontal intervals help stiffen the edging strip against the inwardly directed force of the stretched canvas. Alternately, the cross-section of the edging strip can be extruded in a shape which inherently resists inward deformation, so that the need for separate brackets is eliminated.

Tension in the fabric tightens the grasp of the clip on the fabric margin and urges the clip teeth into engagement with the frame recess grooves. An intermediate frame member having a pair of recesses for retaining the margins of two sheets of sign fabric is also disclosed.

Abstract: A display sign of box-like construction has internal illumination and a face comprising a transparent or translucent sheet with advertising material applied thereto. The face is tensioned by means of a locking element to which the face is attached and which is then forced into the gap between two surfaces. The element is serrated and one of said surfaces includes a detent which co-operates with the serrations. The pull exerted by the tensioned face pulls the locking element into a position in which it lies skew to said surfaces and bears on both said surfaces with the detent between adjacent serrations. There can be one or more locking elements along each edge of the sheet, or one or more locking elements along one edge of the sheet only. The sheet can be tensioned by locking elements acting in two directions which are at right angles to one another.

Abstract: An expandable mesh frame is disclosed for stretching and holding a mesh fabric. The frame consists of four frame rails held together by four corner pieces. The corner pieces fit within the ends of the frame rails to construct the frame and in action with the frame rails provide a selective locking mechanism. When the frame rails are rotated in one direction, as when a fabric mesh is in place on the frame and tension is applied to the mesh, the corner pieces and the frame rail are in an alignment that allows for zero tolerance locking; however, when the frame rails are rotated in the oppposite direction, as when the frame is being disassembled, there is an excess of tolerance between the frame rail and corner pieces. The selective locking mechanism allows for a frame that is easily assembled and disassembled because of the excess tolerance when the frame is in the slack position.

Abstract: In a display or the like device, a flexible sheet is supported in tension within a frame by means of tensioning devices secured to the frame. Each tensioning device includes a movable peg which is engaged in an aperture in the sheet. Each peg can be placed in a position nearer the middle of the space within the frame in which it is retained, or displaced away from the middle of this space, to tension the sheet, and when so displaced, the peg is urged resiliently away from the middle of this space by a spring within the respective tensioning device, to hold the sheet in tension. The tensioning devices thus constitute a simple and compact means of providing for ready interchangability of various display areas in the frame.

Abstract: An acoustic fabric-mounting system includes a fabric stretched across a wooden frame of an acoustic panel. Some frame members are fixed to a wall, while other frame members are connected to one or more brackets which allow them to move relative to the fixed members along the wall. A tensioning bracket mounted beneath the panel exerts an expansion force against the movable frame member, tending to move it translationally apart from the fixed frame member, so that the fabric is stretched taut. The tensioning bracket is spring-loaded and adjustable.
